摘要：

In an ion beam experiment the Coulomb explosion of H+ and D-2(+) in intense laser fields was investigated. The kinetic energy spectra of the fragments H+ and D+ show strong structure at laser intensities close to the threshold. They can be interpreted by net two-photon dissociation followed by Coulomb explosion at a sharp critical internuclear distance.
